AI agents call seneschal_premium_opportunities to retrieve information from Seneschal Data without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though seneschal_premium_opportunities only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Top at-risk borrowers across Aave + Morpho + Spark, annotated with realised 7d market intel (top liquidators, win rate, our own attempt outcomes) and ranked by expected liquidation value. Behind an x402 paywall: free agents see a paywall stub describing how to pay; paying agents fetch the full feed at https://api.seneschal.space/v1/premium/opportunities. Use seneschal_paywall_info to inspect the price/network/recipient before opening a session.. It is categorised as a Read tool in the Seneschal Data MCP Server, which means it retrieves data without modifying state.
Register the Seneschal Data MCP server in PolicyLayer and add a rule for seneschal_premium_opportunities: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Seneschal Data. Nothing to install.
seneschal_premium_opportunities is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the seneschal_premium_opportunities rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for seneschal_premium_opportunities. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
seneschal_premium_opportunities is provided by the Seneschal Data MCP server (https://mcp.seneschal.space/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
